75 moths in the garden trap last night. New for the year were Large Ranunculus, Black Rustic, Grey Pine Carpet and Red-line Quaker, and also this Treble-bar - or is it a Lesser Treble-bar?
The forewing measures 17mm. The moth guides say you can differentiate the males by looking at the abdomen, but I think my specimen is a female. Here is an "underneath" photo.
All help/suggestions welcome.
